In my quest to fill the first page full of zetec questions (joke!), I have another one! lol

Is there a reason why I havent seen any black top engine conversion?, there's a few reason I can think of

1) Cant be done
2) Too expensive
3) I havent been looking hard enough!


Any opinions ?

 

as far as i know the silver top engines are have simpler looms as the black tops have a complicated pats system

I'm sure someone will correct me though

 

i just thought the silver top had more power potential.????

 

I just thouht it was because people had painted the rocker a different colour to match their car/ looks.

Don't know much about zetecs, but guessing they're different colours for different specs like the Cosworth colours?

 

The black tops are different, but not sure how it affects installation into the RS.

the current model Zetec, as used in the Focus and Mondeo is a very different engine to the earlier Zetecs, both visually with it's black plastic cam cover, and internally. Starting at the top, the Series 3 features new injectors - end fed unlike the side fed units on the S1 and S2, and with a twin jet spray pattern. Solid tappets with adjustment shims replaced the hydraulic predecessors and the cam belt timing tensioning setup has been revised. The pistons are teflon coated to reduce friction, and the bearing caps are on a single piece frame to increase strength. The water pump was of a new outboard design, with large vanes for improved flow. The block was strengthened - a larger amount of metal between the bores is clearly visible in comparison with the S1 and S2. The oil filter mounting became integral to the base of the block and the sump gained a windage tray and baffles to reduce oil surge. The sump's webbing was also improved in an effort to combat block flex.

 

anybody else shed any light on how difficult a black top is / isnt to install ?
